Description
Gehäuse für hydraulische Teleskop-Schwingungsdämpfer mit Aufhängeöse, insbesondere für Kraftfahrzeuge Die Erfindung betrifft eine neuartige Ausführungsform des Gehäuses für hydraulische Teleskop-Schwingungsdämpfer mit Aufhängeöse, insbesondere für Kraftfahrzeuge, und ein Verfahren zur Herstellung des Gehäusekörpers.Housing for hydraulic telescopic vibration damper with hanging loop, in particular for motor vehicles The invention relates to a novel embodiment of the housing for hydraulic telescopic vibration dampers with hanging loop, in particular for automobiles, and a method of manufacturing the case body.
Bislang wurden Teleskop-Schwingungsdämpfer in der Regel mit einem Gehäuse ausgerüstet, das aus einem Zylinderrohr bestand, welches mit dem die Aufhängeöse enthaltenden Zylinderdeckel verschweißt oder aber mittels Gewinde verschraubt war. Nach einer anderen Ausführungsform wurde der Zylinderdeckel mit der Aufhängeöse im Spritzgußverfahren hergestellt und dabei gleichzeitig auf das Zylinderrohr aufgegossen.Until now, telescopic vibration dampers were usually equipped with a Equipped housing, which consisted of a cylinder tube with which the hanging loop containing cylinder cover was welded or screwed by means of thread. According to another embodiment, the cylinder cover with the hanging loop manufactured by injection molding and at the same time poured onto the cylinder tube.
Derartige Gehäuse hatten den Nachteil, daß ihre Herstellung verhältnismäßig teuer war und daß die Abdichtung zwischen dem Zylinderrohr und dem Zylinderdeckel gewisse Schwierigkeiten bot.Such housings have the disadvantage that their manufacture is relatively was expensive and that the seal between the cylinder tube and the cylinder cover presented certain difficulties.
Die Erfindung will auf einfachste Weise die Abdichtungsschwierigkeiten beseitigen und unter erheblicher Materialersparnis und Vereinfachung der Herstellungsweise, Verkürzung der Bearbeitungszeiten und unter Gewichtsverminderung eine Gehäuseausbildung schaffen, die allen Anforderungen an einfache Herstellung und vielseitige Verwendungsmöglichkeit entspricht. Zu diesem Zweck wird das Gehäuse nicht mehr aus zwei Teilen angefertigt, vielmehr werden erfindungsgemäß das Zylinderrohr und die Aufhängeöse aus einem Stück hergestellt. Dabei wird die Abdichtung des Druckmittels auf dem ganzen Umfang der Aufhängeöse durchgeführt. Die Herstellung des Dämpfergehäuses geschieht auf die Weise, daß zunächst das den Mantel des Dämpfers bildende Zylinderrohr auf die dem Umfang der Öse entsprechende Länge flachgedrückt wird. Falls nötig, wird das Rohr vorher auf das der Breite der späteren Aufhängeöse entsprechende Maß eingezogen oder ausgeweitet. Beim Flachdrücken, (las unter Erwärmung des gegebenenfalls eingezogenen oder ausgeweiteten Rohrteiles oder auch kalt durchgeführt werden kann, wird ein vollkommen dichtes Aufeinanderliegen der beiden Rohrwandungshälften erzielt, so daß das später in dem Dämpfer befindliche Druckmittel aus dem Zylinderrohr durch die zusammengedrückte Rohrwandung nicht austreten kann. Das flachgedrückte Rohrteil wird nun zur Aufhängeöse umgebogen.The invention aims at the sealing difficulties in the simplest possible way eliminate and with considerable material savings and simplification of the manufacturing process, Shortening of the processing times and a housing design with a reduction in weight create that all requirements for simple production and versatile uses is equivalent to. For this purpose, the housing is no longer made of two parts, rather, according to the invention, the cylinder tube and the hanging loop are made from one piece manufactured. The pressure medium is sealed over the entire circumference of the Hanging loop carried out. The production of the damper housing is done in such a way that first the cylinder tube forming the jacket of the damper the length corresponding to the circumference of the eyelet is flattened. If necessary, will the tube was previously pulled in to the dimension corresponding to the width of the later hanging loop or expanded. When flattening, (read while heating the possibly drawn-in or expanded pipe part or can also be carried out cold, is a The two halves of the pipe wall are completely close to one another, so that the pressure medium later located in the damper from the cylinder tube through the compressed pipe wall cannot escape. The flattened pipe part is now bent over to form a hanging loop.
Im allgemeinen braucht eine besondere Befestigung des Bogenschlusses der Öse nicht vorgenommen zu werden. Es kann aber auch vor Einführung des zweckmäßig aus elastischem Material hergestellten Lagers der Aufhängeöse in den zur Öse umgebogenen flachgedrückten Rohrendteil eine Befestigung des Bogenschlusses am Boden des Zylinderrohres, beispielsweise durch Verschweißung, erfolgen.In general, the arch closure needs a special fastening the eyelet not to be made. But it can also be expedient before the introduction of the Made of elastic material bearing of the hanging loop in the bent to the loop flattened pipe end part an attachment of the arc connection at the bottom of the cylinder tube, for example by welding.
Um beim Zusammenbau den Schaft des. Dämpferkolbens lagern zu können, wird er in einer entsprechend ausgebildeten Manschette befestigt, die dann nach Einführung in das Zylinderrohr am Boden, vorteilhaft durch Punktschweißung, befestigt wird.In order to be able to store the shaft of the damper piston during assembly, it is fastened in a suitably designed cuff, which then after Entry into the cylinder tube on the floor, advantageously fixed by spot welding will.
Die Zeichnung zeigt eine beispielsweise Ausführungsform der Erfindung, und zwar zeigt Abb. i ein Dämpfergehäuse nach der Erfindung in Ansicht, teilweise im Schnitt, Abb. 2 einen Schnitt durch die obere Aufhängeöse und Abb. 3 ein eingezogenes Zylinderrohr.The drawing shows an example embodiment of the invention, namely Fig. i shows a damper housing according to the invention in view, partially in section, Fig. 2 a section through the upper hanging loop and Fig. 3 a retracted one Cylinder tube.
Die entsprechend der Baugröße des Schwingungsdämpfers gewählten Zylinderrohre i bzw. 2 werden gegebenenfalls in ihrem Teil 3 eingezogen bzw. ausgeweitet und dann flachgedrückt. Der flachgedrückte Teil wird zur Öse 4 bzw. 5 gebogen, so daß sich eine auf dem ganzen Umfang der Öse 4 bzw. 5 durchgeführte Dichtung 6 bzw. 7 ergibt.The cylinder tubes selected according to the size of the vibration damper i or 2 are indented or expanded in their part 3, if necessary, and then flattened. The flattened part is bent to the eyelet 4 or 5, so that a seal 6 and 7 carried out over the entire circumference of the eyelet 4 or 5 results.
In der Öse 4 bzw. 5 wird das Lager 8 der Aufhängeöse eingeführt, wobei vorher der Bogenschluß 9 bzw: io am Boden i i bzw. 12 des Zylinderrohrs i bzw. 2, beispielsweise durch Schweißung, befestigt werden kann.In the eyelet 4 or 5, the bearing 8 of the suspension eyelet is introduced, wherein before the arc connection 9 or: io at the bottom i i or 12 of the cylinder tube i or 2, for example by welding, can be attached.
Zur Lagerung des Kolbenschafts 13 des Dämpferkolbens dient eine Manschette 14, die beim Zusammenbau des Dämpfers in (las Zylinderrohr i eingeführt und am Boden i i des Zylinderrohrs befestigt wird.A sleeve 14 is used to support the piston shaft 13 of the damper piston and is inserted into the cylinder tube i when the damper is assembled and is attached to the bottom ii of the cylinder tube.
